I am posting this here because I cannot determine what category this falls under. I initially put it under Bug report but going by the description it does not appear to be valid.

Anyway, I was trying to watch and download the webm below.

However, there appears to be something wrong with it. The browser version of the video seems to have trouble playing at any length, it frequently stutters, stops, pixilates, goes black, charactrs become shadowy and indistinct, and many other things. I have been unable to play the whole video uninterrupted. I have tried watching it two separate browsers.

Downloading the video produces a broken, corrupted mess of a webm which goes horribly pixilated a few moments in and then crashes soon after. Someone else besides me seems to confirm these strange occurrences. This has has happened when downloading the video in two separate browsers.

My computer also seems to have trouble identifying the file and deleting it.

it works fine for me

Stuttering and stopping is usually sign of bad internet connection, as in video can't buffer as fast as you are watching it. I know that using seekbar on many VP8 using videos commonly causes intense pixelation and corruption looking video until it reaches next keyframe, but haven't seen this happen by simply pressing play.

There doesn't appear to be any issues with the file itself, uses VP9/Opus, proper container, yuv420p, resolution divisible by two, etc, etc. Everything is fine, plays correctly with everything.

However have you noticed the tags hi_res and high_framerate on the post? That video is 1080p, 59.94 FPS so as I have higher end phone and gaming PC, this kind of file will have no issues whatsoever. If you do have lower end hardware, that would explain why the video would look corrupted and crash software for you, because your machine simply can't keep up. At that point when it's supposed to so you the third frame, it's still busy with second frame which isn't needed anymore.

See if anything else under "high_framerate hi_res type:webm" gives you same effect to any degree. With that particular post, artist has given out tons of differend versions into several websites where to watch video in the source link, so check those, this is also why I would prefer people to put e.g. artists provided secondary gfycat links into the description so that those who cannot view this demanding content could see it.

I usually check my mentions, so pinging me in the comments works. If you are certain that it's the file that's the issue rather than your hardware, we have flag reason for broken/corrupted files and someone on staff checks on it.

I often see these responds in steam community and even though I know that everyone responding like this try to help, it's not that helpful for those actually having the issue.

Then the next person comes in and claims Windows 10 is the cause of whole issue, even though in the end it turned out that it was missing redistributable which some users had from other games they have played...

In this case, it is helpful to state that hey, it's not a broken WebM. It doesn't help fix the problem for the original poster, but it at least lets them know that it is something wrong on their end.

I know I'm adding nothing to this conversation at this point, but I can also confirm that this WEBM file is displaying properly for me as well. I'm using Waterfox 56.0.4.1 64-bit with the latest Java, OpenH264, Shockwave, VLC and Widevine Plugins installed.

There have been cases where firefox wouldn't allow playing the file, while everything else did. There has been cases where mobile chrome played video in corrupted way while desktop played it without any issues. There has been cases where there didn't appear to be anything wrong, but still tons of users were complaining how they simply couldn't see the video.

Without testing things with setup that user is having trouble with or at least with most used and possible cases, saying that the file works still isn't that helpful. I did try the file with chrome, firefox, edge, opera, VLC and MPC-HC on Windows 10 with everything up to date and on chrome, opera, VLC and google photos on android 8.0 as well as checked that the file didn't have anything funky going on in itself.

Then again, OP didn't state what they were using so even my answer is half speculation as it sounds the same when I tried to watch some HD videos on netbook ten years ago. Worst case scenario they are trying to do april fools prank by sinking my time on this.
